Fastest/best way to recover from a SDMMC TXUNDERR error, and write again successfully?

Hello, we are using the SD Card HAL code on an STM32F7. We are pretty much using the default initializers for the peripheral, which leave us atSDMMC2.POWER = 0x00000003 SDMMC2.CLKCR = 0x00000900 SDMMC2.DCTRL = 0x00000033We have some operations that ...

hi guys, I've been trying to write to internal flash for the last two weeks, and unfortunately, I didn't manage to do so. I worked with the function I have from the library and read in the manual.

I am using the stm32f103 and trying to display a text on a screen via DMA to the USART 2 device. I guess I will turn on the usart2 TX dma (DMAT) request when I need it and turn it off after the current transmission is complete (i.e. in the DMA1_Chann...

Positive Feedback: Resources now also list datasheet!

as I proposed some time ago, now products->Mikrocontrollers->Resources lists also datasheets. That way, one does not have to check the individual product pages for datasheet updates.Some other proposal however is still pending:List the documents newe...
